        True, but I think we both agree that someone who is
interested in BiDi will either be running a localized version of
Windows OR (like me) they are running NT or 2K with the appropriate
"language packs" installed. Either way, the input methods and such
will be present.

        Correct, and we will not (IMO) be supporting those platforms.
You will need a localized 9x/ME, OR NT/2K with language packs.

        If you want to display them, you still need the fonts, which
means you have/need the language packs - in which case you also have
the input methods and you can create them.

        I don't see a problem here - you are running an unsupported
platform for non-Roman publishing on Windows.

        Why would you want to reinvent the wheel? The OS has all the
services (unlike Unix), let's USE THEM!! We don't reinvent GUI
widgets, we don't reinvent graphic primitives - why reinvent user
input handling?!?!
